Abstract

The invention microbe fuel cell consists of box, separating plate dividing the box to positive pole cavity and negative pole cavity, there is a hole on the separating plate, hydrogen selecting film is fit on the hole. In positive pole cavity, there is solution compounded by amylaceum, sodium dithydrogen phosphate and methylene blue, a sealine lid is covered on the positive pole cavity, a positive pole graphite rod is fit on the sealing lid, one end of the positive pole grahpite rod with honeycomb small holes rod is soaked in the solution in positive pole cavity, beer saccharomycetes and the substratum are in the honeycomb small holes. In negative pole cavity, there is solution compounded by potassium ferricyanide and fumaric and ferrous, an end lid is covered on the negative pole cavity, a negative pole graphite rod is fit on the end lid, one end of the negative pole graphite rod is soaked in the solution in negative pole cavity.

Description

technical field [0001] The present invention relates to microbial fuel cells. Background technique [0002] At present, fuel cells mostly use platinum to catalyze the reaction of hydrogen and oxygen. But platinum is a very rare precious metal, and the hydrogen-oxygen reaction is not well controlled and easy to explode. And this type of fuel cell is generally relatively large in volume. Contents of the invention [0003] The object of the present invention is to provide a safe and low-cost microbial fuel cell as a micro power source. [0004] The microbial fuel cell includes a box body, which is divided into an anode cavity and a cathode cavity by a separator. There are holes on the separator, and a hydrogen ion selective membrane is arranged on the hole. In the anode cavity, 8-10g of water is added per 10ml of water. Glucose, 3-4g sodium dihydrogen phosphate and 0.5-1g methylene blue solution, the anode cavity is covered with a sealing cover, the anode graphite rod is f...
